摘要：

The Letter is devoted to the calculation of the two-loop O(alpha(s)y(2)) and O(y(4)) MSSM corrections to the relation between the pole mass of the b-quark and its running mass in the (DR) over bar scheme. To evaluate the needed diagrams the large mass expansion procedure is used. The obtained contributions are negative in most of the regions of the parameter space and partly compensate the positive O(alpha(s)(2)) contribution calculated earlier. (C) 2004 Elsevier B.V.
